[7 Mozart General] Nullstring:
SO TO SUMMARIZE EVERYTHING, HERE ARE THE STEPS TO UNLOCKING YOUR MOZART SO YOU CAN FLASH ANY CUSTOM ROM!

Step 1 - Know your region!

You can check check your region by going to:

2.1 - Extract the compressed file

2.2 - Make a copy of RUU_Signed.nbh and rename it to MOZAIMG.nbh

Step 3 - Make your own Y-CABLE

It's extremely easy to make one. If you have already created or bought one then

Step 4 - Get a 1GB MicroSD Card

Guys, don't be hard headed, just get a 1GB MicroSD card if you want to have a flawless unlocking your phone.

4.1 - Reformat it with FAT32 File System and use "Default Allocation Table"

4.1 - Copy the MOZAIMG.nbh file to the root of your MicroSD Card.

Step 5 - Patch it with GoldCard tool

Make sure that you copied MOZAIMG.nbh

5.1 - Run GoldCardTool.exe

5.2 - Make sure the select HTC MMC is your newly reformatted MicroSD Card.

5.2 - Load GoldCard.img (the file is included in GoldCardTool_0.0.5.7z)

5.3 - If the patching was a success, then you're now safe for Step 6

Step 6 - Get everything setup and prepare your:

PC - Reboot! So to make sure everything is refreshed.

Phone - Take off the battery, put it back, turn in on while pressing VOL_DOWN_KEY + CAMERA_BUTTON until the screen said "USB HOST MODE"

Card Reader and MicroSD Card - Am pretty sure you know what to do

Y-CABLE - Connect your Phone and Card Reader and connect the male usb to one of the USB ports at the back of your PC (laptop? then just connect it)

Step 7 - Kiss your phone because the downgrading process will begin

Don't worry if after connecting, and still said "USB HOST MODE" because it will take about 3 - 5 minutes before the flashing begins. If it didn't start after like, give it a 7minutes grace period, then remove the Card Reader and put it back again. Still didn't work? Go get a new card reader ;)

The downgrading process will reboot your phone once after it said

RADIO: OK then after it reboots, it will go back to "USB HOST MODE" and will say "Loading ..." immediately, if you didn't saw that, remove the Card Reader and insert again .. but again, the flashing will restart so it will go back to flashing the Radio again.

If everything went well, and you saw the "SUCCESS" message, you can reboot your phone and go to bootloader to check the SPL version. If the SPL version was successfully downgraded to 1.## then it's you lucky day! You can now move on to Step 8

Step 8 - DFT's RSPL and HSPL

Download those and refer to their manual http://xdaforums.com/showthread.php?t=1195647 . If those didn't go well, then make sure you read everything it saids on their manual.

If that goes well, confirm it by rebooting and going to the bootloader, and you'll see the "HSPL" instead of "SPL" then the version.

If you saw the "HSPL" then you're safe to flashing your first

CUSTOM MOZART ROM!

If everything went well, you can have your Mozart unlocked with less than 30minutes
